AUTOMATIC EXTINGUISHER FOR LAMP BURNERS. APPLICATION FILED APR. 22, 1904.

UNITED STATES PATENT canon SIMS LEVER, OF SYDNEY, NEW SOUTH WALES, AUSTRALIA.

AUTOMATlC EXTlNGUISHER FO R LAMP-BURNERS.

To alt whom i1; may concern:

Be it known' that I, SIMS LEVER, dental surgeon, a subject of the King ofGrreatlowing is a specification.

This invention relates to. improved attachment to oil, oil-gas, and the like burners for automatically extinguishing such burners in case of overthrow or other accident, and

though it has been specially devised for application to the burners of hand-lamps it may also be applied to any burners, fixed or otherwise, Where there is danger from accidentor jar which will cause ignition of escaping oil or other fuel or-other material by the flame of said burner suffering the accident or jar.

This improved attachment to oil, oil-gas,

I andthe like burners for automatically extinguishing such burners in case of overthrow or other accident consists, essentially, in de tachable lever or radiusbar with the turnscrew of the wick or fuel-supply tube, a

weighted ball, a circular seating for said weighted ball of smaller size than the diameter of said ball, and a chain or cord connecting the said detachable radius-bar through said seating to the weighted ball, arranged thatas the weighted ball falls from the seat' ing, which it is adapted to do on the tilting or overthrow of the burner or on the jarring of the same, it pulls-upon the chain and by means of the radius-bar turns the adjustingscrew and diminishes the height of the wick in the burner-tube, and so extinguishes it.

The radius-bar in other arrangements by its motion will turn the cock or tap of the fuelsupply tube, and thus extinguish the burner.

As an illustration of the application of this 7 invention to the best use the same will now be described with reference to the drawings herewith, in which Figure l is an elevation of the burner of an ordinary oil-lamp having these improved attachments; and Fig. 2 is a reverse sectional plan of the same, taken on'the line 2 2 in Fig. l. v

low bulb, and it has orifices 4 through it across the center, adapted to receive a slightlytapered lever or radius rod or needle 5 and allow said needle 5 to be easily and quickly detached for rearrangement of the wick as to its height in the wick-tube. Instead of a needle end passing this orifice in the turnscrew end this inner end of the needle-bar might be a clip or spring catch to take firmly over the end edgewise or over the stem. To

the outer end of this needle .5 is attached a chain 6, reaching through a guiding-eye 7 and upwardly through circular seating 8 to the weighted hall 9, which seating 8 is considerably smaller than said ball 9. The eyefrom passing too far through the pair of orifioes 4, in which it is inserted after the wick is adjusted. The slack of chain 6 allows of regulation as to height of wick within all necessary limits, and it is needful only occasionally to detach and reenter the needle 5 in the turn-screw end 8. The ball 9 merely rests uncontrolled thereby on the seating 8 and will fall therefrom on sensible jar or upon tilting or overthrow of the lamp or burner. As said ball 9 leaves said seating 8 its weight sharply pulls, the chain, and. this draws the needle-5 over, and this movement revolving turn-screw 3 at once lowers the wick in the wick-tube and extinguishes the flame. When the seating 8 is not hollow, as shown, the eye 7 is an essential, but when said seating is hol- -low it acts as a guide for the chain and the certainly do so before lodgment should the lamp be thrown or be jarred or jerked to any distance.-

Having now particularly described and as certained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is In combination with a burner, a turn-screw for regulating the wick, said screw having an enlarged substantially cylindrical head hav- In testimony whereofI havesigned my name ing transverse orifices therein, a needle adaptto this speclficatlon 1n the presence of two subed to loosely fit 1n said orifices, a chain sescrlblng Witnesses.
